First time broody Muscovy has been sitting on eggs for close to a month now and suddenly pushed out 2 eggs from the nest this morning. Those eggs had live ducks in them so I popped them in my incubator. Went out tonight and she had pushed out another. Egg was cold and I thought duckling was dead, but still alive so added to my incubator. Why is she suddenly pushing eggs out when she’s been so good about sitting? Do I take the other 3 from her and put in incubator?
